Effects of Herbal Vitamin D3 and Phytase Supplementation to Broiler Feed on Performance, Bone Development and Serum Parameters of Broilers

Abstract

A trial was conducted to assess the effects of phytasesupplementation and substitute Vitamin D3 resource withPanbonis - a herbal vitamin D3 source- (PAN) on performance,some carcass characteristics, tibia and serum parameters ofbroiler chickens. For this purpose, 11200 one-day-old, mixed sex(5600 male, 5600 female) Ross-308 chicks were administered 7different diets based on corn, soybean and wheat throughout the41-day trial. Dietary treatments; control group as T1 (5000 IUvitamin D3), T2 (T1 + 500 FTU g-1 phytase), T3 (3000 IU vitaminD3 + 500 FTU g-1 phytase + 100 mg kg-1 PAN) and T4 (3000 IUvitamin D3 + 500 FTU g-1 phytase + 200 mg kg-1PAN) wereprepared to contain recommended levels of Ca-P however T5, T6and T7 were formulated from T2, T3 and T4, respectively, byreducing 18% of Ca and P concentrations.When overall results considered, there was no significantdifference among treatments in terms of final live weight,mortality, weight gain, European Production Efficiency Factor(EPEF) and carcass parameters and mortality (P>0.05). Whilebirds consuming diets containing phytase exhibited better FCRthan control group without phytase (P
